If you want a publish/subscribe framework, I found freebase, which is the core of the freeride ruby IDE, elegant and powerful.

I'll be greatful.
If what you're looking for is a simple non-distributed
observer pattern, Ruby includes one in the standard library.
Check [1] for the documentation. The example usage on that
page is actually a simple stock market!
Otherwise, if you're looking for a distributed solution,
check DRb [2] (Distributed Ruby) and Rinda [3], Ruby's
implementation of the tuplespace paradigm. It's not classical
publish/subscribe but can be used to do the same kind of things.
[1]
http://www.ruby-doc.org/stdlib/libdoc/observer/rdoc/files/obse
rver_rb.html
[2] http://www.ruby-doc.org/stdlib/libdoc/drb/rdoc/index.html
[3] http://www.ruby-doc.org/stdlib/libdoc/rinda/rdoc/index.html
Actually what you would probably bemost interested in the FreeRIDE's
Databus. This is the basic pub/sub class. FreeBASE (which build on top of
the Dtaabus) is a dynamically loading plugin system.
You can read abot both of them here:

Sorry for all the typos... I had just gotten out of bed.
